Where the parcel data comes from
This is a statewide map, not a county site. Montana Cadastral (Montana State Library) covers parcels across Montana, and Sheridan County is one part of it. Statewide parcel layers are usually stitched together from county files, so the newest splits or sales may show up on the county's own records first. When we tested the link in October 2026 it opened with no login and no fee.
